[solved] 1.1.3 or 1.1.4 OTB downgrade error
The trick is how you set the iPhone into recovery mode. If you are unable to restore the iPhone to 1.1.1 then this post is for you:
In your step 1 of any jailbreak/unlock method, you must set the iPhone to "restore mode". For 1.1.3 and 1.1.4 OTB you *MUST* do it like this:
Press BOTH buttons (home + pwr) for 10 seconds (count them!).
After *exactly* 10 seconds release the pwr button while still holding the home button. After 15-20 seconds, the iPhone should go into recovery mode (you will be notified by iTunes).
Now you can downgrade to 1.1.1 succesfully.
Please note that I had to downgrade *TWO* times in a row, in order to kick the iPhone out of recovery mode (I used iNdepence).
As highlighted in the link below, this has worked on 1.1.3 & 1.1.4 OTB 8GB and 16GB iPhones!
